Advantages of Gravity Die Casting Services
Reduced Thermal Gradient Effects
In gravity die casting, the molten metal is poured into a preheated die, which helps maintain a uniform temperature across the casting. This reduces thermal gradient effects and minimizes internal stresses and defects such as warping and shrinkage.
Enhanced Mechanical Properties Due to Controlled Cooling
The process allows for controlled cooling rates due to metal dies, which helps achieve a refined microstructure. This controlled solidification can enhance mechanical properties like tensile strength and fatigue resistance by reducing the formation of coarse grains and promoting uniform crystal structures.
Precise Control Over Metal Flow Dynamics
Gravity die casting enables precise control over the flow dynamics of the molten metal. This control reduces the likelihood of air entrapment and ensures that the metal fills intricate die cavities, improving the cast parts' overall integrity and dimensional accuracy.
Improved Die Life and Dimensional Stability
Using high-quality, heat-treated dies in gravity die casting extends the life of the dies and maintains dimensional stability over multiple casting cycles. The thermal and mechanical stresses are evenly distributed, reducing die wear and ensuring consistent part quality throughout production runs.

Our Gravity Die Casting Process
The metal die is cleaned and preheated to a specific temperature to prevent thermal shock and ensure uniform metal flow. A release agent is then applied to the die to allow easy removal of the casting.
Molten metal, typically aluminum or another alloy, is manually poured into the die cavity using gravity. Gravity ensures a controlled metal flow, filling the die evenly without external pressure.
As the metal cools inside the die, it solidifies. The controlled cooling process helps achieve a uniform structure, reducing internal stresses and improving the cast part's mechanical properties.
The die is opened once the metal has fully solidified, and the cast part is ejected. Care is taken to ensure the casting retains its precise shape and dimensional accuracy.
After removal, the cast part may undergo minor finishing processes such as trimming excess material, surface treatments, or machining, depending on the application's requirements.

Gravity Die Casting Materials
Gravity die casting uses various metals to produce high-quality components. The choice of material depends on the components’ requirements, such as strength, weight, and corrosion resistance.
These are commonly used due to their lightweight, good mechanical properties, and corrosion resistance. Aluminum alloys like A356 and 319 are often chosen for their strength and durability in automotive and aerospace applications.
Zinc alloys are ideal for complex shapes and thin walls because they are known for their excellent fluidity and reproduction of fine detail. They also offer good mechanical properties and resistance to corrosion, making them suitable for electronic and precision components.
These alloys are selected for their high strength-to-weight ratio. Magnesium is used in applications where reducing weight is an important factor, including aerospace and automotive industries. It also offers good castability and dimensional stability.
copper-based alloys, such as brass and bronze, are used for their superior mechanical properties, including high strength and wear resistance. They are suitable for parts that require good thermal and electrical conductivity.
Enhancing Casting Efficiency with Gravity Die Casting
Gravity die casting provides precise dimensional accuracy and smooth surfaces, reducing the need for secondary machining. It allows for thinner walls, enabling complex shapes, and directly integrates inserts like threads or heating elements into the cast. With higher tensile strength than sand casting and rapid production rates, it’s ideal for longer production runs, especially in aluminum casting.

Having Doubts? Our FAQ
Check all our Frequently Asked Question
Gravity die casting works well with metals like aluminum, zinc, and magnesium. These metals are light and have good fluidity. They fill the mold easily, making it easier to create detailed shapes. Their low melting points also save energy during production.
The temperature of the molten metal is crucial. If it's too low, the metal may not fill the mold, leading to weak spots. If it's too high, it can cause defects like gas bubbles. Keeping the right temperature ensures strong, high-quality parts.
Mold design is vital for gravity die casting. A well-designed mold allows the metal to flow smoothly and cool evenly. Features like vents and risers help release trapped air and ensure the metal fills all areas, reducing defects and improving part strength.
Cooling time affects how well the metal solidifies and how strong the final part will be. If the cooling is too fast, the metal may crack. If it's too slow, it can warp. Finding the right cooling time helps achieve the best dimensions and mechanical properties.
Surface finish in gravity die casting can be controlled through mold treatment and design. Using coatings or polishing the mold can improve surface quality. Adjusting the pouring speed can minimize turbulence, resulting in smoother surfaces. This enhances the aesthetic and functional properties of the final product.
